use solvent guns for water-based paints?

[mcondos]

Hi all,
I'm getting ready to get into painting, and am considering buying several Sata HVLP guns to start with. However, I've read that the industry is going to solvent-free product in a couple years. I've also read that guns used for solvent-based paints cannot be used for water-based product, even after proper cleaning, due to contamination issues. Is that true? I don't want to drop $1500 on guns to have to throw them away in 2 years. Should I buy cheaper guns till then?
Thanks for the advice, this site is awesome!!

if a gun has never been used for uro's it's no problem..

hwever..if you use uro's in a gun and want to switch to water based or waterborne paint..clean the gun thouroughly with reducer or laquer thinner,
then hot soapy water..clear water, then denauterd alcohol..no trouble.

I use Auto Air Colors exclusively...good stuff.
