Lily it deopends opn what you buy
Our first tent cost £35 pmslin the sales so wuld only have asted a year anyway, but the Gelert (a Tahoma,like the Diablo 600 in many ways) was worth buying as it did a good frew trips and resold well on Ebay
TBH tents such as Outwell,Vango, Khyam QE imo are Premium Tents. There's abcolutely no ned to have one and most other brands are justa s good. It's like the difference between a Proton (good car, we had one for ages) and a MErc: functionally no difference but if you're intocars them there's a wow factor.
You wont go wrongwith most name brandtents,as long as your hh is over 3000 and it's pitched OK. It can howevertakeawhile to work out exactly what you want from a tent and for thisreason loads of us on here upgraded annually until we found the 'perfect'one,and that's only done through experience I think- and taht's when its worth investing £500+ in a tent.
I do have a suggestion for you, we loved it and I didnt elaise Khyam were still selling it- the Khyam Ontario 8. Worked brilliantly for 5 of us, premium brand decent price and DH could put up single handedly.ANd yes a SIG always a SIG here LOL. And it has a decent resalevalue too if you choose to move on- webought for £199 lanch year, sold for £150 after severaltrips.
