pressure vs. siphon blaster

[Vallely <code5@banet.net>]

Hello--
Just got a Sears 'Auto Shop' catalog full of Eastwood products. They
have some interesting looking particle blasters.
Has anyone out there had the opportunity to compare a siphon with a
pressure sandblaster? My little Sears siphon-type outfit is too slow and
clogs easily. Is a pressure-type as much faster as the catalog claims?
Thanks for any info / advice. They aren't cheap, so I'd rather look
before I leap.
