Has anyone heard of them and are they any good? They have a siren with 20 programmable tones. I have used Autopage in a previous install and also have had a Viper, Python, and Code Alarm back in the day. They were all pretty good alarm systems. I don't care for DEI's 6 Tone siren, but may get their alarm and SkyTek's siren or just go with Skytek altogether. They are www.skytek.net .
