[TenTec] Can Iambic be used as single Paddle

[designer]

My last key was a J-38, so many decades ago. Now I feel the cw itch 
again but the world has changed. From reading these posts about a 
week ago, and my experience with demos at ham stores, I think I'd 
adopt to a single paddle faster than iambic. That is, I understand 
index finger/thumb pressure, but squeeze trips me up.

However, there are few Bencher ST-1/2 or Vibroplex Keyer models for 
sale. Almost everything I see in classifieds is iambic. Can the 
iambic be "adjusted" so it ignores the squeeze? I'll be using this 
with and Argo V and/or a Paragon with an outboard keyer.

I picked up an MFJ 407B but hear they are touchy over 20 wpm. Is the 
MFJ 408 any better?
