Thanks all, you’ve basically confirmed what I was thinking (buy something new). Given that I’ve just bought my Tarmac and I’m going to be out of the country for most of next year and will only take the Tarmac with me, I’ll likely have a look around in the end of season sales next autumn / winter and see what I can pick up - should have a bigger budget by then too. Will likely be back then asking for some more advice!
Thanks again.
