[quote name='Tyga24']I was also considering buying a used 360 arcade and was wondering what chipset was in the Arcade version with Sega Tennis I believe from 2008. I am wondering if there are any drawbacks to that particular model and if I should get the current arcade version with the 512 MB internal memory instead (I would be getting the used console for around $100). Thanks, and any help/recommendations is appreciated.[/QUOTE]
With a 2008 model, it's more than likely a Falcon model. Which is more prone to the RROD than a Jasper model. One way to tell is voltage that it uses. If it's a 175W, it's a Falcon model. If it's a 150W, it's a Jasper Model.
If you're wanting a reliable one, it's better to just buy a new Arcade version. You'll get a 3 year warranty, the 512MB memory(that 2008 won't have any memory built in) and won't be worn down like the used one is.
