Most, if not all, of the no swap chips have 23 wires to solder....Because like Warlock said They are all just Messiah clones... To do everything that these mod chips do, require alot of connections.....Take the USB mod.....Yeah, you can play certain things.....BUT it takes a GS/AR2 and a swap, and you still cant play everything.......
As far as being cheaper....... Figure it like this..... Go out and buy 2-3 original games.....(You have just paid for a Messiah or a clone plus installation)
So they are REALLY not very expensive after all.....
AND if they get the clips finalized, it will be that much easier to install.....
