Sinar P 8x10 replacement bellows options

hello,
I am looking into buying a set of replacement bellows for my sinar P 8x10. I have a set of bellows frames i can use. I was wondering if any one has had any experiences using the bellows sold with out frames on ebay. It seems to be all from one guy who ships them from hong kong; the price seems reasonable. This leads to my next question, what is the right type of glue/adhesive to attache the new bellows to the frames?

contact cement works fine, mix in some charcoal dust to make it black, and help with light-fastness

A friend of mine got a 4x5 set of bellows from one of the HK dealers, and the workmanship was top-rate, and the price was very economical. She was very happy
