Used Titus Racer X mountain bike (ebay): $1379 including shipping
New Shimano XT crankset for said bike since I need 170mm cranks, and it came with 175s: $272
Other bike shop tuneup stuff and labor: $$?? (not sure yet, I pick it up Tuesday!)

Yes, it adds up - but it is money well spent in my book!

Oh, I should also add that I recently made $750 selling one of my road bikes, so that helped offset these purchases.
