If you don't do sports photography, you really don't need a 7D. That said, the 60D is not intended to be used by professionals. It has no auto focus micro adjustment. It has a mostly plastic body.
Unless you mostly shoot in RAW, and print pictures larger than 8x10, the 60D would probably suffice.
Since you seem concerned about losing money to depreciation...and you already bought a 60D, then sold it, then bought a new 7D for a relatively low price, I would just cool it on buying anything else. You're already seeing a lot more depreciation than if you had just bought the one camera and kept it, or else waited and bought a 70D or a 7D II.
As for what looks good in your hands...frankly you're being silly and shallow a bit. Nobody is going to be looking that closely at a crop camera body while it is in your hands, or be able to tell the difference...they are similar in size (maybe between a rebel and a 7D, yes...but not a 60D). People who know, are looking more at what lens you're using anyway.
If you're mostly doing video, anyone who is familiar with that, would be looking more at your sound rig and tripod, or otherwise your cinema grip.
