Here is how I did mine cheap and easy. I only have about $150 in the entire hoist/track system. I posted this in my garage makeover thread a few months ago:
Electric Attic Hoist on Barn Door Track:
Loaded with over 400lbs of car part boxes (brake rotors, coil-over springs, struts, starters, intake manifolds, etc.)
Video of the hoist in action:
The electric hoist is from Harbor Freight. It's the 1100lb/500lb unit for $139. Then it was on sale for $99 in a magazine, then I used a 20% off coupon from the same magazine for a total price of $79. For the track, I got the 450lb rated stuff from McMaster-Carr. I bought two 8' sections on sale for $18 each and two trolley's for $21 each. I decided to skip the mounting brackets that they said were required every 2ft and on the ends (which saved me $130) and just drilled holes in it and ran 3.5" decking screws straight into the 2x6 in the attic. I just loaded it with screws (12 per 8' section, spaced 1' apart and doubled up near the ends) and it works great.

I've since used the pulley that comes with the hoist to double up the line which cuts the speed of the lift in half which makes it smoother and easier to control. I've lifted 3 engines with it, tons of boxes full of engine parts, brakes, suspension components, etc. and it's done it without issue. I think it's the most useful part of my garage makeover. Being able to move it side to side 16 ft once I lift into the attic is very handy as well.
