No bottom feeding atty yet. No, I haven't tried the REO out yet.
I have looked at the offerings at Reomods.com, but I can't afford nearly $50 for an atomizer.
What is your vaping preference ? 10- 12 Watts ? 50 Watts ?
Single coil ? Dual Coil ? Exotic coil conglomeration ?
Your vaping style would help us point you in the right direction. Also, could you describe / post a picture of your new (to you) Reo Grand ? Older models require different attachments than the newer Reos.
Aaand ... Welcome to Reoville !
