cold feet about potential bad lifters

The melling lifters are at a price where I can buy the summit cam as a stand alone and then buy lifters and come out at the same price as I was before, so that's compelling for me since this is essentially a stop gap before I build a motor to put in the car. That being said, at that price point I wouldn't be surprised if they're identical to the summit lifters but I know nothing about either company's manufacturing lines.
The lunati seems to be a more confidence inspiring option but is pricier. Cheaper than buying multiple sets of lifters after one set flattens though.
Three reman route is interesting but I might just do that after I swap the cams to have a good set on the shelf for later.
I can't find the comp 270s, every time I look it up I get Chevy cams with 270 duration
