I know Ringmer well (live fairly close by) and have had friends and clients living there.
Many people I know call it the Village of the Dead, it is so bloody dull. The only interesting things that have happened in Ringmer in the 29 years I've lived in the area were when the firework factory caught fire and a group of travellers set up camp on the village green. A friend who lived there says that the best thing about it is that last bus back from Lewes is late enough for you to get a pint at last orders in Lewes and still catch the bus home.
Ringmer has 2 pubs, a truly grim chain pub and a slightly less grim non-chain pub. It has a busy main road running through the middle of it and horrendous traffic in both rush hours. The primary school isn't all that and people try and get their kids into the one in the next village north. There's been a lot of new development and more going on, and the population was well over 6,000 some 20 years ago, I wouldn't be surprised if it was approaching 9,000 now.
It has 3 things going for it: a very nice Indian restaurant, a good and reasonably priced beauty salon and a decent cafe that does a nice breakfast. Shopping is very limited, you'll need to go to Lewes (which has 3 supermarkets, but all small) or Uckfield (decent sized Tesco, tiny Waitrose) to do a "proper" shop.
There are plenty of nicer villages in the area. I'd suggest looking at Plumpton, Newick, East Hoathly, or even places like Fletching and Mayfield if being further north/east isn't a problem. In west Sussex, I rather like Steyning and Henfield (which I think is a small town, rather than a village, but still not much bigger than Ringmer), but I think house prices are higher there.
Or you could consider the outskirts of Lewes. The estates on the outskirts have decent sized gardens and good access to countryside. The area known as Nevill, up near the old racecourse, has family houses with decent sized gardens for under £500k (which sounds insane to me, but won't to someone from Brighton).
