Coincidentally, I had the same thoughts after I got mine, so I'll share what I learned from Randy at Vega. They have a 24" travel midi, and it costs $379. However, if you already have the 10" model, they will sell you what you need to make it a 24...for $75 :eusa_clap(and you will still have the 10 as well):eusa_danc:eusa_clap; basically it's a longer extrusion, longer chain and an extra bracket. That's just an FYI and I'll let you do the math.
I ended up buying a bigger, Pro model for my Nova DVR XP and am happy as a clam. Good luck to you. If you're interested in mine, just let me know.
