Hi Robin,
Reading Allocator's reply I'm almost the same.
Had SBS-1 for over a year and was happy with the hardware, but not so happy with the software and the constant need for third party utilities and no network option built into the system.
I was a pre-order customer for Radarbox and the reason I ordered was because its software had everything included in one system including network option.
Not saying that the Radarbox software is perfect, it is better I think than SBS-1 basestation but can still be improved.
Not as yet purchased the 3D option of Radarbox or for that matter the live network, but this maybe something I'll look at soon and only because I had a year out of monitoring due to other commitments.
If I was to purchase a unit for the first time now what would I go for, more than likely Radarbox. Again for the same reasons based on software, although mlat would be a feature that I'd have to think about hard.
At the end of the day all units are doing the same thing and the biggest difference (for me anyway) is the software.
I sold my SBS-1 when I was happy with Radarbox, but I do wish I'd kept it, but the only reason I'd be using it now would be for Mlat, with Radarbox still being the main set.
