For parts store parts (and parts store prices ~ $130 / side)
I feel like Empi axles are as good as any reman.
(though my experience is almost 90% watercooled)
I remember when the local German parts haus used to sell me Lobro remanufactured axles for like $75-80 per side (when I first got a mk2 in 96 or so,)
And for the last few years, they usually stock Empi.
Last time I got an axle, i got a FEQ
("First Equipment Quality" was the name brand!)
total cheap chinese crap,
but I threw it on this car, and no issues yet (~1000 miles)
Just my .02
