Get a set of Eibach/Spoon springs with that budget. Cheapest coilovers I would buy are AST's and they are around £1100 or so the last time I looked.
I have D2's and a lot of my friend have them too, I have had no problems with them and compared to the Tein Monoflex I had they are great. Cost isn't the ending factor as my £600 coilovers out perform my £1900 ones without even trying. I agree you get what you pay for but not in all cases.
If you want a decent road set up then BC or D2's will do you well if you want a track set up then AST's would be a better option.

Just had a group buy on FD2-owners, £1500 fitted.
What about Eibach Pro-Streets?
Last I knew, they were £800, but, that was before the recession kicked in, so they may well be more expensive now. Tom rates them, but he says for road use, the Eibach springs are more than up to the job.
Anyone on the site running these?? ^
