Pros and Cons... Which model

[MrAnderson85]

Well im new here and was originally getting myself a 2004 RXP 215... But things came up and that fell through. Now im looking at some newer models. I found some decent deals on a few 08's brand spaking new.

My questions are what are the differences and pros and cons of these models... Besides the HP differences.

1: 09 RXP 215
2: 08 RXP-X 255
3: 08 RXT-X 255
4: 09 RXT 215

Thanks
