Do you know the quality of these?
What would you recommend for me?

you may get the oroginal 1600i Kat completely with exhauster for a bit more then the ebay offer directly from Volkswagen CLassic Parts.
I bought one a year ago for approx. 460€ incl German VAT
Part number is 043 251 063 C http://www.vw-classicparts.de
Give it a try.
