Best gravity, hand held sand blaster

[timex69]

Hey
i was searching ebay and came across some hand handle sand blasters, i was wondering if anyone here has used them and what they reccomend. Im getting some new tools for my shop and I would like to have a sand blaster but i figured some feedback on them wouldnt be bad. Let me know what you have and the kind of luck you've had with yours.

I actually like the gravity fed blasters. They don't waste sand as much as the pressure pots but take alot more time to blast parts....

My dad has one that I use and it's called a speed blaster it works excellent, here it is:)
