Because last year I only purchased enough parts to make 4 boards (whoops), I recently had to buy VGATonic components again. We've had a few price increases over the last year (and some minor drops), so this is as good a time as any to update our Bill of Materials. Some of these are last year prices (since I had 10-20x of some).
Assuming you buy enough components to make 10 (like me):
$20.53
I spent around $3.08 a board in shipping total, but you can beat that. There are also 95 cents worth of options (technically some of the resistors are optional too in the RCA output stage - I don't have a firmware using it yet).
If you are lucky/willing on eBay or with non-authorized stock or pulls, I have no doubt you can do ~ $15 - but I, of course, encourage ordering new/authorized for support reasons.
