Aeroweld exhaust - any info?

Hi all, 

It's been asked on here before but no reply back then so hoping someone has now had some experience, but, has anyone come across Aeroweld exhausts for the Rotax 912? Czech based company. 

I'm in need of a new exhaust system but costs for new units are quite prohibitive IMO but Aeroweld seem quite reasonable at under 500 euro. 

Thanks!

Tom.
