.255 will not work because it is the broadcast address for the 192.168.1.0/24 network.
Simply choose one high up in the range, it will *never* conflict, you'll be OK.
I would go for .200 or something easily memorable.
If you like you could go into your router and adjust the range down to .2-199 for example so it would never conflict, but I strongly doubt you'd ever plug in 199 devices anyway to make it conflict.
