I have a Paasche VL and I really like it.
It's a vary versatile brush that's easy to care for and very popular. Quite the work horse.
The down sides:
Detail: You can get some Badger and Iwata brushes that will put this thing to shame while still being able to handle wider areas. The Paasche VL is a very versatile brush though. But that is comparing a siphone feed with gravity feeds.
Pressure: The VL takes more pressure to atomize liquid. So you'll be spraying at a slightly higher pressure than other possible choices. This will only be an issue if you have a VERY wimpy compressor.
Pros:
Durable, easy to clean, easy to get parts, etc.,.
Popular and time tested design - beloved by airbrush T-shirt artists
Versatile - with the right needle in place you can spray almost anything.
Common - should be able to find a deal on it. They're still recovering from Katrina, but defintiely check out dixieart.com if you live in the US. Free shipping and a great price.
Hope that was helpful,
