I spent about 6 months trying to figure out which of three portable mounts to buy: Vixen portamount with HAL130 tripod, Bintel/GSO Skyview alt az and the Skywatcher Skytee 2.
The Skyview has a stronger head than the Vixen and the arm can be mounted at different angles and on either side of the mount. The HAL130 tripod is stronger than the one supplied with the Skyview.
Here's a link to the porta with hal130:

However I ended buying the Skytee because it's more solid and can carry a greater range of telescopes. I bought the Canadian Telescope Duo T version because Andrews is having trouble getting the Skytee in stock, though they're saying it will be in by November. The head fits straight onto the tripod supplied with HEQ5 mounts.
