Actually I would recommend you to move to a server where they offer ddos protection at the network level. Specialized HTTP filtering is quite expensive, and not commonly offered by companies. For instance, try contacting www.gigenet.com or www.staminus.net or www.awknet.com. All three are specialized on ddos protection and might help you with it.
One customer of mine was having similar problems on his server (it was a dedicated server), he then moved to theplanet where they say every connection is protected by cisco guard, and it seems to have stopped, I'm not sure if it was the protection or the change of ip, but he seems happy enough now.
This protection is just banning identical IPs and this may, in most cases, ban a legitimate user who is not trying to DDos you.
Having mentioned that I think that eugeniopacheco's post comes right on time.

This would be the best thing to do in such cases!
We have to mention one very important thing which is regarding DDos Deflate. This solution so to speak is meant to handle small attacks. When we talk about attacks from a major csale the picture is totally different. DDos deflate is incapable of dealing with massive attacks and that is 100% sure.
It performs the filtration on the web server level and limits the queries to just one IP.
And when this number exceeds the capabilities of the server - game over
There are many vps hosts who are under your price range who will give you better specs then what you have for a lower price, Such as jaguarpc, and they will happily help you with ddos attacks if price is what your worried about
