kraze, the "burst" RAM tells us that he's looking at a very different class of VPS at the other host. Anything with "burst" RAM is not going to be Xen-based and is going to have significantly more clients sharing a box. If the other host forces him to use a specific OS, they're most likely using OpenVZ. Their low price stems from the fact that so many customers are put onto a single machine and so much RAM is swapped to disk; the lower the price, generally, the more customers and RAM-swappage you'll see. Both of these lead to low and unpredictable performance, which is why we use dedicated cores and no virtual RAM at all here. We talk a bit more about this topic here: viewtopic.php?f=47&t=4940
ITZ_MOH, you should be able to construct a 1-core package with 2 GB of RAM through our order page, but it might be a better deal to just get the 2-core one. It might seem strange, but our 2-core VDS product would be much faster than any dedicated machine that you can find with one or two cores (as any such machine would be ridiculously old and slow).
