Hey if you do buy one I can help you out if you ever need it, I am in nova 20 minutes from DC and do almost all my maintenance myself. Take the plunge, you won't regret it. Changing the oil on the XFire is easy, I do it myself for about $45 dollars, it is a breeze. Plus it would be nice to have another owner in this neck of woods (i.e. DC, NOVA).
