Don't, just don't.
If it wasn't for a stranger from the US who I encountered on a forum, I would be out the money paid for the conversion as well as my A100 + lens.
As has been heard in previous reviews (Insiderpages among others), he communicates well up to a point. In my case it was until I sent the camera. To make a rather long story short, I waited three weeks after tracking showed it had been received by Spencer, as repairs could take 'ten working days'. Right, he replied after a few days, saying 'Good news! We just received your camera! We expect to ship it tomorrow and will send tracking# then.' Okay..
I hear nothing for a few days and email again to ask. Nothing, email again after a few days more. After 1.5 weeks I get pre-shipping info from USPS, which shows electronical shipping info was provided, nothing else.
After that I email and I call (no reply, leave message on answering machine so that they can 'get right back to me').
I never heard from Spencer's again, but after this friendly person on a photography forum called them and actually got a reply ("We've been busy with training") and called them again the camera suddenly appeared, after two months of them having received it. The work was pretty good.
