Thanks all for your replies. I ended up getting an older second hand machine (2003 Heller 1707 EXL) from a local company upgrading their assembly line. It is in mint conditions and was used in air conditioned room and had maintenance every 3 months.

Roni: Ron gives good advice on the thickness of your Electroless Nickel - Immersion Gold (ENIG) solderability preservative. Several additional comments are ENIG: � More expensive than OSPs and HASL. � Much flatter surface than HASL, similar to OSP
