hi balamorybaby, there are loads of us having boy/girl twins now. anyway i had the icandy apple and thought it was ok but wasnt convinced at the quality. i didnt get the pear because just too many people said how heavy it was and the seats were very small. people on e-bay seem to be selling them after a few months which is never a great sign. i just really wanted the chassis so i could put the maxi-cosi car seats on as well but its alot of money to spend. if you get a cheap one on e-bay then you could try it and re-sell it if you hate it (and possibly make some money) the cheapest one i have seen was £250 buy it now and it was only on there about 5 minutes.
i have tried loads of doubles out as my two are under 17 months apart. the moutain buggy urban was by far the best for me. it depends what you want to use it for. we go to the beach and in the muddy woods alot so the maclaren type buggies were a waste of time. my friend with twins had a maclaren twin for years but they dont have a car and live in the city, so it was great for busses etc. i have a secondhand twin maclaren techno this time as my second buggy to the MB urban because it might come in handy later on going to twin toddler group which is in the city and far from the car park (and its less likely to get stolen) it will also be handy for trips to the doctors as its more compact. my main buggy is the mountain buggy urban with twin carrycot, its actually narrower than the maclaren but longer. as i said i had one before and loved it, they are pretty much indestructable. mine cost £90 from e-bay and £60 for the carrycot.
other buggies i have had, m&p aira (not very good quality and bulky) jane powertwin (tendancy to tip with a toddler in the front) jane twin two (really big and heavy, terrible wheels) ABC everest (excellent buggy but no carrycot, big plus is you can add a toddler seat on as well) easylife twin and single with toddler seat (really heavy and chops your fingers off when folding)mutsy with duo seat (really hard to steer and really heavy and wide) phil and teds E3, sport and twin (overall great buggies but not as great quality as the MB). i have probably had some more but i cant think of them at the moment.
if you have other children as well the mountain buggy can take two buggy boards and you can push it with one hand. my second choice is the ABC (adventure buggy company) everest. you can have the single with the reclining toddler seat for twins or the twin version with as many as two toddler seats on top. its lightweight and just as good as the mountain buggy. the only downside is that they dont do a carrycot and the twin MB carrycot is lovely.
see if you can get to a big baby shop and have a good look at the twins available. if you decide on one look on the internet as places like kiddycare often have them cheaper. also as long as you can remove the covers for washing, e-bay is a great place for cheap secondhand buggies. there are also some on mumsnet, netmums, tamba, preloved and the adtrader. i got my secondhand maclaren twin techno from a secondhand baby shop in norwich. it was in excellent condition with all the accessories still in sealed bags and it was £70.
i believe it is sometimes better to get a secondhand good quality buggy than a new cheap lower quality buggy. i saw a lady with 8 month old twins in TKMAX with a twin hauck buggy. the wheels were so buckled the buggy wobbled around like a broken shopping trolley on a roller coaster. it certainly put me off hauck buggies, it cost her £399 and didnt last 8 months!!!
