Need a Good VPS Panel under $15

Since HyperVM already has no updates for a while and it can take a while before the known and unkown exploits are repaired we have builded a temporarily control panel. But we want to have a serious solution which compares to the prices from HyperVM ($0.50/VPS), what do you recommend?

We have already found VDS manager from ispsystem.com, but still we are searching for another solution which may be cheaper (else we have to raise the prices from our VPSes, the last thing we want to do).

HyperVM is free and good control panel, also you can try SolusVM, vePortal, etc..

SolusVM has a good style ;)
