which should i consider

If you can afford a 2009, which is the first year of the non IMSB, do that, and eliminate that potential problem. If you need to buy an earlier Boxster, make sure that the IMSB update has already been installed, or plan to do it immediately after you get the car (about $2k). There may be a lot of hype about this, but why gamble - make it a non-issue and then enjoy! Good luck.
