Cheapest RDP? Thoughts?

For days I gather information about the cheapest RDP on the market and this is what I've found.
Currently, am at hyonix.com

Now, these three are offering the cheapest rdp on the market. (ram wise)(core wise)

https://amazingrdp.com (best choice so far)
https://vpsgod.com (this is good but always out of stock)
https://wishosting.com (i don't know if they are real)

How about you guys what's on your thoughts?

I can vouch for wishosting.com - definitely a legitimate web host.

Not that I have used any of these, but the first one looks better.
