There have been a lot of excellent comments about the effectiveness of cyclones. They are nice, but they're also expensive. Maybe someday when I have the $$$ and something besides half of a garage. Right now, I'm using a shop vac with 2 1/2" hose that I roll from tool to tool. It's better than nothing, but it misses a lot.
Today, I was walking through the blue borg and saw a delta 1hp/600cfm boasting a 1 micron filter, on wheels for under $300. Every time I see a roll around DC, it's tempting, but temptation is a poor reason for buying a particular brand.
So... Just supposing you were retired, on a fixed income and couldn't afford a cyclone... What would you buy for around $300 that has decent pick up and can be rolled around the shop? Almost anything would outperform a Craftsman shop vac, but I'd also like it to last a while, which rules out things like the ultra low cost HF units. Any and all suggestions will be appreciated, and I'm sure, helpful to a lot of folks. Thanks in advance for your help!
