roller rockers and solid roller lifters

Hi guy's, just a few quick questions

1. Does anyone know how good the quality of the "off brand" rockers are that I see for sale on ebay? I don't want to waste my money on junk. But at the sme time I don't have a ton of money to buy the expensive name brands like from Comp Cams I want the 1.6 rockers for a 440 BB.

2. Does anyone know where I can get a set of solid roller lifters for a decent price? I want to get Comp cams solid roller cam 23-701-9 with 570 lift and need a set of lifters to go with it.

3.Does anyone know how well the 1.6 rockers will work with this cam and lifters, the motor will see mostly street use with a trip to the drag stip every now and then?

Thanks for your help and any suggestions are appreciated.
