Continental USA only.
Here are a few things that you might could use. Prices not including shipping, but generally these are small and will only cost about $2 to mail in a padded envelop.
Spirit bubble level $30
Rapid wind crank, one has some writing on back. $10 each
Correction lens +1 diopter for PM/PME finders $10
Sport viewer $10
Accessory shoe/flash adapter $10
Rear cover Multicontrol 51070 w/instructions LIKE NEW $10 nice to have if you have critical viewing needs
Quick release tripod adapter Yea, this is rough but it works. You can see the cork on the bottom is gone but I've used it like that with no problem or you can just glue some on. $10
Also, I am going to be selling my SWC kit soon... PM me if interested.
Thanks,
