I had the Steeda shifter and bushing in my '12 Boss and it was nice, easy to install, worked pretty well but it didn't prevent the high rpm lockout on upshifts (especially 2-3). I have an MGW on my '13 Laguna and it is perfection. Beautiful shift action and no issues at all with gears being locked out. It is a little tougher to install but nothing serious. It is well worth the extra money. There are several threads about shifters on this site if you want more info.
Take a look at what you get with the MGW as opposed to the Steeda, not to knock Steeda's stuff or the quality, however the MGW seems to be the total package. Most other shifters seem to come with just the shifter and then you have to buy the bracket also, where as the MGW comes with the upper and lower, and now they even have an adjustable bracket.
