I too have a MEPL rating on a fairly low houred (300+) PPL and I really enjoyed the challenge of training and flying it on longer trips abroad. I always flew it with another equally qualified pilot to share the workload and lighten the costs also as I didnt feel 'that' confident to go alone, we had fun and learned a whole heap.
However, it worked well with other like minded folk and freinds around, I had to move away due work and I've let it lapse as I cant justify the expense as I would basically have to start the process over again, finding new freinds (who I trust to fly a multi with) and a not so expensive twin.
If I could tick those boxes again, I'd go back to flying one tomorrow.
