If you mean was your sarcasm difficult to follow, no, not obtuse - abstruse or obscure, maybe. Depends on the reader.
As far as the OP's self-described minor gloat - nice way to rain on his parade. You ignored the Rockwell clamp - the point of his post - the Crapsman thing was clearly meant as an aside. The Rockwell Jawhorse thing is well regarded, and for $60 for a new one it qualifies as a minor gloat.
The corner clamps are another matter, and it's not clear exactly which Craftsman corner clamps the OP bought. Craftsman has a new Bessey knockoff that goes for ~$25 which is about $15 less than the Bessey. I haven't seen the Craftsman one up close, but if it's reasonable four of them for $40 is also reasonable.
