Affordable VPS Hosting with multiple server location choices?

[Rombello]

Dear members,
I am in need of a VPS hosting service with access to multiple server location choices. 
Ideally, the provider should deliver consistent speed, strong network stability, and professional support. 
Features such as easy scalability and clear service terms would also be valuable. Monthly budget is 20 USD. 
Is Hostpresto.com vps hosting reliable? Recommendations from your personal experiences are welcome.

Accounts from just.hosting and operavps.com are worth every cent you pay for their services.
Count me a satisfied customer. They are cost-competitive and service oriented.
