yes, i agree, the messiah 2 pro or ripperchip is the best current mod although a cheaper alternative should be the magic 3 but if possible go fo the messiah 2 pro
by the way watch how much you pay if you buy it from a fitter the m2 pro chip is a very small (tiny) thin board and is much cheaper than the old messiah chip i dont know what the single unit price is but in the uk the go for around £30(each) for 10 or £20 (each) for 100 so you shouldnt have to pay over £50 including fitting from most places that treat you fairly (expect £10-£15 more if its an older model ps2 like a v3/v4 or jap 1000 or 1500 model)
