I know the feeling
I am in exactly the same situation and have thought through all the above options many times and can't decide on the best one!
I am swaying towards getting my MECR because if the situation arose where I needed to fly a twin at short notice (I can't think of one but you never know!) I would like to be able to.
You could try posting this in the jobs section, most people who read here are either doing training or about to, whereas those in the 'desperate for a job' section will be in the same boat.... aircraft... whatever!
