As I have Travelites for sale all I'll say is that just remember, the AB800's are only 320 w/s. Even the 1600's are only 640w/s. The Travelite 750's are 750 w/s. And the modeling lights are 250-275 watts instead of 100-150 watts as they are on the AB's.
I'm not saying the AB's aren't good. Many use them with great results, and I have used them. It's just that you are comparing the AB800 and Travelite 750. I want to ensure that you know that the output is not the same.
those do look nice... and good price. One Travelite goes for 600.00, I got the kit with umbrela, stand and case for 670.00. Only good news my photos have improved 100% over my old strobes so im happy...and broke! Large low profile softbox makes all the diffrence in the world.
