I Just picked up an Arcan xl35 today at Costco.
It is great for our FDs...as the clearance is only 3.5", yes, that means it just fits under the front end of a stock fd and rols to the cross-member with ease.
and it was only 79.00.
You have to love costco sometimes....
anyone else see/have this?

 

i got a craftsman one...it works good but clearance is pretty high, it barely fits under a stock fd...imagine it dropped a few inches...
