This isn't about price comparisons, it's about ROI

At best your unit will return 35 BTC

You are charging 57 BTC (at today's rate)

but you are being a nice guy, letting people finance it a little for 10% interest a week. Look at my avatar picture, did you learn your interest compounding from someone like that?

Terms are as follows:
1) 25% of total once per week on agreed set date.
2) 1 BTC interest per week 
3) If you fail to make payments or no longer can make payments, you will forfeit whatever you have paid and the machine. I am very understanding about 1-2 day delay if given prior notice, however don't make it a habit.

 
4) or you send Rocco over to see me???


I wish you well but no one with a calculator is going to bite I am afraid.
I understand you have $2500-3000 in chips in each one of these but I can't justify $7500 there is just no ROI unless BTC goes to $225 then I just break even.
