Well, asking specific questions here that only the vendor can really answer is kind of silly, imho. The vendor is going to give you the only answer you can use to make a decision.
What's to stop me from telling you that yes, the price will change, when in fact... it might not?
With regard to asking about an *opinion* of a company.. then yes, this is the right place.
Uptime and reliability of our vps with the other a2b2 company has been very good, considering the very low price we are paying. We've been with them for over a year now, and have had no problems other then the occasional network hiccup, which is to be expected with any provider.
I have no problem at all recommending them.
