As you already have mechanicals in your watchbox, a quartz particularly a smp quartz could be a nice complement. I was in the same situation a couple years back and decided to try a 2264. I have to admit it took me awhile to get over the idea of wearing a quartz again. However in terms of looks, ruggedness and ease of use the smp 300 quartz is just a fantastic piece, and I wear mine regularly now, and exclusively for sports. For your budget, you can definitely find a next to new example if you're patient. Yes, you may find an older smp 300 auto in that range but it'll almost certainly be well used and could well need service, so you'd want to factor that in.
