Hi,
A larger resovoir is better to have. The smaller tanks will lose pressure more quickly as you spray and the motor will need to come on more often to fill it up. This means the pressure fluctuates more often and that can be detrimental to your spraying job.
I have a 50litre tank but most of my spraying is air-brushing and this uses little air and pressure and therefore the motor doesn't switch on too much. However, an air brush requires less pressure than a full sprayer (that you will need) and the cut-on pressure (to recharge the tank) is more than what the air-brush needs, so I don't notice it.
Also, the bigger tank allows for more variety of tools and I can attach not only a spray gun, but also air-hammers, air wrench and air-nailer and riveter.
A 50ltr tank is a little more expensive than the smaller units but it allows more tools and versatility. They cost from around 130-200 dollars, which isn't much and put out 150psi. I suggest you buy the 50ltr unit and spend a bit of money on getting a decent spray-gun. Poor/cheap ones will allow the paint to come out blotchy and uneven.
And, keep the spray gun mega-clean at all times, 'cos a little bit of shit or dried paint in the delivery system can cause major headaches and uneven paint etc.
Hope this helps.
