It certainly may be worth that money to the right buyer but if it were me I'd find something a little cheaper. As you've said earlier, it's just for your home lawn and you're not looking to mow daily or achieve a putting green, so it probably isn't worth looking around for even better machines.
I come across Rover/Scott Bonnar 45's for sale all the time in good condition for a lot less than that, and whilst many are not in such nice condition cosmetically they have been well maintained mechanically over the years and will still have years of reliable use if maintained in the future. With a sharpen and service they cut and work very well. The other bonus is that spare parts are easy to come across.
I bought one of me SB45's for $70 in good condition only because the Briggs had no spark and the owner couldn't get it going. It took me 10 mins to fix that once I got home and less than $100 for a sharpen and some oil and a plug. If you're prepared to take your time and hunt around you can definitely get a good bargain. Out of interest, what part of QLD are you in? If you're in striking distance to Brisbane there's usually plenty of model 45's for sale each week. If you're further north they get a little thinner in numbers.
Cheers, Michael
