Sprayers Electric vs. Air vs. foam roller

hi myx. I also used rollers for my cab and it turned out great, smooth and shiny. I used the fine finish rollers and latex paint.
I gave it 3 coats of latex primer and three coats of black semi gloss latex. Like dot said surface preparation makes all the difference in the world. I used a belt sander loaded with fine grit sand paper and sanded everything smooth between each lair of paint and primer. It makes a huge difference in the final appearance. I also used a new roller with each coat of paint to avoid any thing that may have gotton on the rollers. It's not exactly necessary but whats a few extra bucks for extera rollers when your already sinking a ton of cash into a machine. Here's apic of my fineshed cab, You can click it to see a fullsize

I spent a while doing housing rehabs and sprung for a highend airless sprayer.  It set me back nearly 2K but the high psi lay on a nice finish.  Being airless, it also offered an even coat throughout all my painting projects.  There is a downside though.  First off the over-spray can't be ignored.  You MUST protect surfaces that you don't want painted or you will have a big mess on your hands.  Speaking of messes, cleaning and priming can be messy as well.  The only other downfall is the amount of paint you have to use.  I would venture to say I use 25% more paint with the sprayer vs. hand painting.

All that being said, I love my sprayer and fear the day is breaks down on me.  Although as many people have eluded to, you get what you pay for (maybe even more so with paint sprayers).  So if you don't see a need (and have the resources) to drop a few bones on one piece of equipment I suggest you don't bother.

Doc Thirst:

Damn, spaced out one of the best stories I have about painting.  As I mentioned I did a stint in rehab (no not THAT rehab) along with my cousin.  My cousin is kind of a free spirit to put it nicely.  Well anyways I was painting in one room and had him monitoring the sprayer and paint supply in the other.  I guess in the process of dragging the hose into the other room I caused a small puncture.  Well paint was spraying everywhere so my cousin in all his wisdom opted to thumb the hole instead of just killing the sprayer.  Well 2500 psi does weird things to a human thumb.  In a split second his thumb swelled to twice it's size, filling with paint.  Instead of going to the doc he just squeezed as much paint out as he could.  Over the next few weeks his injury got worse and finally ended up with him in the hospital.  Although he kept his thumb and still has full function, it still looks really creepy.  His career as a hand model are clearly over.

Well ... it was probably 180 or 200 as I recently moved and that's all I remember seeing for my orbital.  Don't hold me to that as it's been ~1 year and I'm having trouble remembering last week.

mmmmmmm shiny. Nice job.

I am leaning towards oil, but I think that the roller has it. My orbital sander seems to leave ruts. It is like you can see that it is sanding but there is an additional squigly line that is also left behind. I am thinking that some how a screw is poking throught he paper or something. I have touched the surface trying to find whatever is causing it but can feel nothing out of the ordinary.
