As we know, expense can be extended, or reduced, depending on your circumstances. I've reasonably finished with my expenditure. My last major expense is the shed to house it all in.
As my age continues, I understand that there are certain time limitations upon me. Do I splash out on the latest 'must have'? Or, do I enjoy what I've got? There are one or two 'must haves' that I will buy, purely because I've said that I will buy when those models finally turn up. Those sad people whom read my posts will know which ones.... I really like the idea of a Heljan 47xx, or a Big Lizzie, but they never ran in my area. By the same token, no P2, or Flying Scotsman, etc.
So yes, it can be expensive, but if you're realistic, it doesn't necessarily need to be so.
Some of these modellers spend £10, and make it look like a million dollars. Now, they impress me no end.
Happy weekend,
Ian.
