Well, what I don't like about LODs with caps is that most of the ones in market use the 'big' dock with straight cable. I wanted to use a low profile LOD (right angle, small, cheap and good quality on ebay) so the rig fits in my pocket as you say. To make this possible, you need to wire the caps inside the iPod housing, like my one. And this is basically only possible (or easy) with Tarkan's CF adaptor as it leaves enough space on the bottom corners inside, and you need to use small BG caps (47uF) or small types of Nichicon or Silmic.
I believe RWA doesn't do the imod so that BG caps fit in the housing. They will probably also try to rip you off by selling LODs with BG caps built in - but any of those straight cable LODs is not pocket friendly imo.
If you still want RWA to do it for the resale value, I won't stop you, but there's no guarantee that you will end up selling it for enough $. Look at the for sale section where people try to sell their RWA imods for so much, and they're unsold for quite long. Also, since good players reasonably priced are coming up recently (X3, eventually X5, DX50) I have a feeling market interest will shift towards them.
Anyway you can PM me if you want more info for the DIYmod I done.
Sorry for no photos folks but I'll probably post something when my TWag cable replacement arrives.
