After market Timing belts, whats good, whats not, opinions please

[Aidan]

Hi guys, I'm hoping to change the timing belt, along with the inj pump belt, tensioner, idler, crankshaft pulley oil seal and water pump in the next week or so. I phoned all the Volvo Dealer's in my area, as I would prefere to use genuine Volvo parts on something as crucial as a timing belt. Acording to all that I contacted the Timing belt is about $85, the inj pump belt is no longer available, the tensioner is almost $100 (ouch) the water pump is no longer available, and no one knew if it did or did not have a idler. So, with that in mind I'm going to have to buy most of the parts from an after market supplier. I'm thinking "Gates" or "Contitech" as they seem to have a good reputation. For the belts what one of those company's would you advise, bearing in mind I want belts that match or exceed OEM spec. The timing and pump belts were changed at a Volvo dealer 40k miles ago and I have reciept to confirm, but cant find one to say if the water pump, tensioner etc were changed as well so I am going to assume they were not and fit new ones while I've got it apart. I'd like to get a kit if possible but will buy individually if no kit is available. Any commets, advice, suggestions etc would be very welcome, thanks guys,
Aidan.
