Sean,
I have some opinions:
I love my baja and will never be getting rid if it in the near or late future. Having that truck bed is so invaluable that it makes life so much easier.
The tonneau cover from soa is really over priced in my mind since it is just a piece of vinyl that is pulled tight (by hand no less) and some cheep plastic. you also have to drill holes in the bed rales to mount it, so that was out for me. I have not seen mutch in the cheeper market. The snugtop is running something like 1300, I am not sure about the ozzbros, but I think it is about 800 (I could be wrong), and the ARE cap is about 1500 (I think). I have the ARE cap with the keyless entry on it and love it. I know that it makes it look more like the outback but having all of the volume makes all the differance for me and being able to lock it as well.
The soa subwoofer I haven't heard in a long time, but though it was a little on the pricer sides for a sub. I have installed the clarion srv303 in the same place and it has more power and you can get it for less than the oem one (as long as you install it yourself, if not, probally about the same or a little more depending on the installers). I love it and it sounds great with my Pioneer DEH-550MP (I think that is the model of the top of my head). The stock system isn't great, but it is good for most stock systems in my opinion. I have not upgraded the speakers at all, but my turbo premium came with the subaru upgraded speakers and everything seems to be really well ballanced.
both of our baja and forester have meet our outdoor lifestyles really well. We like to do some hiking, biking and camping, and oo yes, some 4x4ing. I have gotten my baja in places that most 4x4 owners were saying "how the hell did you get that here". This little trucklet is so versital that it keeps amazing me constantly. I am about to move and most of the work is going to be done by the baja so will have some pics to post of what we get in it.
One tip is get the skid plate from
http://www.rallitek.com. It was the best thing I have gotten. It makes the front end so much stiffer and it provides that much more protection agenst anything evil protruding out of the ground that wants to attack your oil pan.
