Super cheap...and they seem to have the equipment needed as well as the skills and workforce. Why not support them and keep the service going. http://lab2104.tu-plovdiv.bg/index.php/2015/12/12/price/ GB
Compared to B&W they're not bad for labour at all...the parts charges look pricey when you c/w to belts from Marrs and idler from ESL etc. Recap can't be that expensive for parts, so why not supply the parts, then have a clean/lube/reassemble and recalibrate. Including carriage, parts, labour, and VAT it's got to be no more than half for the same effective service. Or, DIY and then just have it recalibrated and carriaged by return. That's the cheapest and most effective I'd say.
It's cool to see an actual repair service back in operation. We might have a few around here but they're mostly old school guys doing time with 3-8 months of backup. I like that they list their equipment and pricing is fairly straightforward. I thought this might be a good business incubator idea here since electronic repair is disappearing fast. I had a local record shop ask me if I wanted to oversee a bunch of youngsters to help them fix the boxes of electronic equipment they get as "donations" I don't have the time but I would be fun, although my repair experience is limited even though I love doing it. The pricing does seem to be high for some of the services, around here you can go to the university and they basically work for free if you pay for materials since it's for education.
