I hear ya on parts adding up.
Getting the exact lugs one needs can be tricky too as the lug style on this set has 3 different bolt hole spacings used over the years on different model drums. And the spacing I need is not listed in Ludwigs parts catalog or on parts web sites. Just the Lugs seem to run $10 a piece, etc.
I only need 3 lugs and 6 tension rods to fix up our 13" tom. ( heads are maintenance cost items anyway, got 2 of them coming from sweetwater for $24 shipped )
I ran across an ebay listing for a single smaller tom in the exact same model as our set. $20 buy it now. I grabbed it. Now I'll just transfer the lugs, rods, washers, etc. I'll take what I need and put it back on ebay.
You don't have any double bass pedals lying around that you don't need do ya? I've been eying the Tama Iron Cobra, but they hold their used value pretty well. I know, champagne taste on a beer budget..
Once my son crafts his skills on this kit I'll upgrade.
