[sdiy] Heat Gun Recommendation?

[Sam Ecoff]

Hi All,

Can anyone recommend a heat gun for shrinking shrink wrap tubing?  
I've been using an aim-n-flame, which works acceptably so long as I'm  
very careful, but I'd really love to step up to a real heat gun. I  
need something I can aim in a very localized way because I often  
place shrink wrap around the lugs of pots so that they don't short on  
a frac rail or accidentally touch a bare ground wire. I found this  
one at American Science and Surplus (very fun store to browse in!)  
http://www.sciplus.com/recommendation.cfm/rid/54376 but I'm not sure  
it's right for me. I'd appreciate any pointers any one can give me.

Thanks,

Sam E.
