Thanks guys for the nice reviews!
I've been testing the mini SLG 2 prototype over the last few days, and am just about ready to send the files over to have the boards printed.
The big change is that there will no longer be two different versions ("PC" or "Arcade"). Instead the mini 2 is a universal model with 2 modes, selected by a small switch. Mode 1 is recommended for Arcade hardware/consoles, and Mode 2 for PC/MAME.
The mini 2 will also feature an "off" setting, to completely disable scanlines. The unit is turned off by selecting the center position of the Mode switch.
The last change is that the mini 2 will be more stubby, and a little wider. The shorter length will help with tight spaces (like inside bartops), and will cause the unit to protrude less from PC video cards (less potential for cable strain).
I expect to have the mini SLG 2 ready for sale in the first week of August. The cost will go up slightly to $26 to accomodate an increase in production costs. I still have a few pcbs left for the current version, and will continue selling those units at $22 until I run out. If you already own a mini SLG, I'm planning on offering a special discount so you won't have to pay full price, stay tuned
