I use Kato points with the motor built into the ballast.

Just as an example, the Peco scissors crossover needs 4 point motors, it's wiring is complicated and the RRP is £49.00. The Kato scissors crossover on the other hand has built in point motors and uses only 2 wires to control everything with an RRP of £41.99. MG. Sharp are one UK stockist of Kato Unitrack.

There would only be one loco going over the scissors crossover at a time, so it would either be set as straight, or cross. The built in point motors do that for you. The price examples I gave were the full prices from two of the major UK retailers. I mostly by mine from Plaza Japan like Nick, where they are much cheaper, when they are in stock. There's now a UK based Ebay shop ( fastrack99) that sells the Kato Scissors Crossing for £38.65.
