^ That was gonna be my reply.
First off I have no experience with Oade's gear. I ran a busman UA5 for a couple years and it sounded great. Damn near everything i've run has been modded by Busman in some way; Busman Naks (sold, want back), Busman UA5 (sold), Busman 660 (still own), Busman Avantones (still own) and have loved every piece of busman gear.
But with the small difference between the price of a modded UA5 ($300ish, granted they were going dirt cheap awhile ago) and then maybe 100-200 dollars more to get a great all in one box (used), for me it was worth it to skip that extra piece of luggage and have it all in one. Mics, Cables, Recorder-all set. It's worth it.
