Which Aneros Model is best for me?

Don't hesitate. Get the SGX. If you are short (I am 5'5") the other models are a real stretch (I guess the pun is intended). The SGX may be the most under-rated of the Aneros tools.

Really? Cool! Is it smaller than the Helix?

Agree, SGX. Very mobile and I like the ribbed stem!

Fifth grade dictum, "it's not the pen, it's the penmanship."

I'm 72" , average trunk length, 180lb. The following was a session that wasn't aiming for an "O" and I thought the SGX wouldn't reach my prostate.

Strictly a Newbie. Usual tool in a Helix but sometimes use Progasm.

SGX got me my first Dry-O:

I would suggest using the Peridise first or buy the MGX and Peridise and alternate using them then skip to the Progasm when you feel ready.
