i am the DVD guru (or at least i like to think i am)
1. headshotter, your analysis of DVD+R is complete and utter crap, to say the least, it all depends on media, burn quality, recorder, and reading drive. for example, my XBOX reads DVD+Rs just fine, why? because i have the Phillips model DVD Drive in my xbox, however, my friend has the samsung model, and can only read DVD-Rs, my PS2 can read my DVD+Rs, my PC and all PCs i have ever tried do, and a cheap RCA DVD Player from radio shack can as well.
2. eagle, to answer your question, right now, the best bang for the buck "AMD" of the dvd burners (not like plextors, the Intels of the market, always paying more than what you get) is the Pioneer DVR-108 (OEM) or DVR-A08XL (retail and 2x expensive for no reason). newegg has both in stock, i am actually selling my 107 for a 108, the 108 has 16x DVD+R and 12x -R i believe (again headshotter, dvd+r is alot better than you make it look) and it also does dual layer DVD+R (headshotter, show me some dual layer -R why don't you)
have fun with your new drive, whatever it is you decide to get
