Reel to Reel Machine for 15 ips playback

I see some Otari MTR10 1/4" for sale on craigslist in Denver.  Not sure if this would work in the home environment?  $3500

Thank you both for your help and recommendations.  

I'm really just starting to think about this so I haven't thought of a budget.  I've bought a few tapes from Acoustic Sounds as I do like the idea of the tape format and was worried about the buy now or cry later.  

The Mara machines at Acoustic Sounds are $10-$14k.  Is that a good budget or does it need to be $20-25k?  

I'm in the rocky mountains of Colorado.  

The ones I bought are the Analog Productions Ultra Tape 1/4 inch 15 ips.

Discogs says 2 track stereo

What kind of budget would you expect to find a used ATR-102 both in good to excellent condition?  Also does AK have a website for his hot rodded units?  What kind of budget should I expect to spend on a hot rodded unit?
