I agree with you, mad_jock - timing is all, and the more tools in your box the better!
However, the market is not indicating a need for the low hour MEIR jockey, and IMHO, unlikely to do so for a good few years.
An indicator to move up an engine will be when the large pool of mid houred newbies with MEIR, currently flying SE VFR taxi services start to be shown an interest by carriers. Then, I believe, would be the time to upgrade. In the meantime, you are IR current, RT current and maybe MCC positive. (Do you have to be ME to do MCC? I cannot remember...)
