Looking for small VPS' in different locations...

I've asked this a couple of times before, but I'm broadening my range a small amount!

I'm making a large update to my monitoring script I have made, and including external servers to monitor.

What I need;

Small resource servers (64->256mb RAM :: 2-10GB Disk :: 50-100GB+ BW)

What I have already;

I have small servers in - NL, US, UK, IT (LES) and FR (i-83 - Thanks!)

I'd preferably like different locations to the above, although a couple of secondary monitors are not bad!

I'd prefer to pay yearly and the max I'd like to pay is around $20-25 per annum. (at most)

Thanks in advance!
