Propshaft balancing

[qwertyu]

I have an H reg 320i E30 coupe with 117k on the clock. It used to vibrate between 60 and 70mph (but I could 'drive through' it!)so I got the giubo and propshaft bearing changed. But now it starts to vibrate as soon as I reach 30mph! I've given up on the mechanic who did the giubo replacement and I wondered if anyone knows of a reliable company or garage that could balance and refit the propshaft for me in the London area? That seems the logical next step. It's well beyond me to fix it myself but I need somewhere that comes recommended that I can trust to completely solve the problem. Any ideas?
Thanks

I have same experience with you last year change bearing and balancing but it become worse so I ended give up and buy used propshaft.

But may be there has good qualified machine shop?

Indeed, Markus, that's what I'm looking for. I just need the problem solved. I've had 2 E30s before this one and hever had a problem with the drivetrain. So if anyone can help with a garage that could provide this repair I'd be very grateful to hear about it.
Thanks.

Thanks for that - although my antivirus blocks the site with a 'threat detected' message! I ended getting a secondhand propshaft fitted which seems to have worked.
