Over the summer, I'd ordered a 10-pack of EVODs from Fasttech (< $2/each). I know they're clones, but I don't have any issues with them. I didn't care for the heads that came with them (and I rebuild my own), but they've never given me a lick of trouble.
As mentioned above, get "better" coils and if not leaking, let 'er rip. The major bummer would be if you paid too much for it....
