Hey Danny, just thought I'd throw in some more two bits.. "magnetic" actually doesn't tell you whether it's pulse-start or probe-start, as both are still the "transformer and capacitor" style (or "magnetic" if you prefer). Basically the way to tell them apart is what their ANSI code is (e.g., M59 or M135 or whatever) but failing that the other way to tell them apart is count the components: probe-starts are just the transformer and capacitor; pulse-starts are transformer, capacitor, and ignitor.

As for your question though, have you looked into a Radium?

If you have pulse starts, the Radiums would be nice

If you have probe start, XM 20Ks are nice, especially for their price.

I'm running the XM 15K's and they're quite nice too... again for the price... I've also liked the Ushio 20K's and they fire on a non pulse ballast, but are more expensive... I've seen a lot of people having success with the Radiums though, and heard that they hold their PAR/spectrum far longer...
