We had the same pricing issues about Spaun, and then our proud local AVAD started telling us they were having reliability issues, so they sold us Eagle Aspen...or we found them somewhere else...

Since the dishes with built-in multiswitches count on receiving 22 kHz from the receivers to indicate LNB B and C, you can use those outputs if you can send tone up when you want those signals.

Eagle Aspen has four- and five-input by four and eight (and maybe more) output multiswitches that send tone as well as voltage up the line, so they can be used with dishes that have integrated multiswitches. If the multiswitch does not send tone up to the dish, you will always get LNB A.

Just used the fourth eight-output one. Worked like a charm.

However, you have TWO cables. That means you have to use stacked outputs. I don't know if the outputs just normally come out of LNBs stacked or not, or if you will need to add stackers. Then, down below, you will have to unstack and plug the unstacked signals into a multiswitch. That is messy but doable.
