If it were my money i'd go M&M. They are are Romanian like the WASR but all the ones i've seen have had consistent clean work unlike the WASR.
As for IO inc I don't care for them as company. They have had bad customer service to me personally in the past (FAL kit I bought from them) plus they IMO changed their name from Inter ordnance to IO inc to escape their bad reputation which BTW stems not just from customer service but workmanship. Maybe they run a better operation these days(I don't care to get bit twice) but given the choice i'd would go M&M or look for something on the used market.
On a side note IO inc's PPS43 and polish archer get good reviews but they also didn't do any of the work on the PPS43 and only conversion work on the archer.
Practical before tactical.
