Wow! Many comments, much of them valuable; learned a lot, truly. Not that I'm making a summary, but one point is clearly missing...
Decision making is a matter of binary logic, either you go for it, or you don't. From the theory of systems, for that kind of decision you must have one universal "efficiency" criterion, which is, inexorably, money.
(1) Write down all the comments in this thread; number them;
(2) Write down all your own thoughts, along the above comments;
(3) Assign weight factor to each of the above; bring them to a single dimension (e.g. money);
(4) Count -- an you get your decision.
(5) If still unsure, go to #2 (perhaps you failed to materialize an idea of yours in a formal way);
