It's about as cheap as it gets for a good VPS. There's a million billion vps hosts out there and most of them are all either over-priced or the vps's are just horrible. The only 2 VPS companies that people really talk about on here for botting are seerhost and photonvps, both good, seerhost is cheaper though and will do the job just as well.
VPSs definitely aren't cheap but I think you'll find Seerhost is significantly cheaper than other providers. Also, don't be tricked by extremely low prices on websites- they can name whatever price they want since they can oversell their resources (poor performance for you)
