I'll make a comment on that, that might be relevant.
I have a budget for this hobby and think carefully about what I buy, I am reluctant to place deposits on items as it ties up my available budget, this may look like I don't have the money to buy anything and yet the invoices I paid in January amounted to just short of £20,000 and we're looking at spending money this month on a holiday as well as work. Does this mean I have £50 for a deposit....no, because it's a different budget.
