Basically, to avoid being damaged laser diodes need a constant, regulated amount of current flowing through them. This circuit that regulates the current is known as a driver. If you are looking to spend 20 or so, I doubt that you would be able to get a good-quality driver. Without this your laser runs the risk of dimming/brightening with heat changes, and having a very short life. In theory a resistor limiting the current and a capacitor to abssorb "surges" should be enough to protect a laser diode, but it is very far from a precise science, and heat will affect the output and current. In my opinion spending a little extra and buying/building a proper driver is well worth the extra cost.

Default Best places for cheap bluray/violet lasers

Could be... even the 2500 sony bluray player doesnt support SACD <- which is a bit of a worry.. none of the current sony lineup support it and id have thaught they would out of anyone.. so either its being left to dedicated players maybe not such a bad thing, or its the end of the road for it.

Cheers,
Bitey

yeah for 20 euros you could buy a PHr-803T sled, and a REALLY cheap host that you will have to modify yourself, not to mention harvesting the diode and removing it from its stock heatsink. then pressing it into an aixiz module. but without a driver i recommend saving your money and buying one of Jayrob's Host/heatsink kits and then add the HOT OPTION, wich is where he adds AND calibrates a flexdrive for you. so all you have to do is solder the diode to the driver, and put the host together. but your looking at about $100 for all that, maybe more depending on the diode.

lasers "ecspecialy blu-ray" should not be rushed. i have a bag of seven dead diodes totaling over $150 in value that i have to see every day, and its because i didnt wait and be patient. just a word of advice. do it right, and always use a heatsink and a good driver.
