My honest advice is for anyone considering an aftermarket replacement board of any type is to search for one that uses through hole parts. Surface mount repairs are not for the faint hearted and generally are not a 'hobbyist' repair , if repairable at all.
Buy a board with SM parts actually puts you in a poorer position than when you started, better to look for a used original IMO.
New Sterns are going to cause some massive (read - expensive) problems when the SM boards start playing up, SM technology construction simply is not and was never intended to be repairable. I'm not saying that it can't be done just that it is usually beyond the means available to hobbyists and the parts themselves are difficult to find.
Buy surface mount - you will be buying another if it stops. Yes, you heard it first here...........
