I take it 134V's purpose is to get a straight, flat face as opposed just getting a better surface finish. The problem with hand held planers is that they will not flatten a timber in and of themselves. I found this out when I got my first Makita 6-1/4. You have to determine where more material needs to come off and work at it. The way to get it flat without having to study each piece, is to have the workpiece stationary and the planer stationary in the vertical as you make a pass. I've also seen a couple of people modify bench top planers. The problem with that is power and speed- not enough of either. The real answer is a setup that does what a joiner does. The one tool I've seen that does this is a Norwood LM410 log molder. You can install straight planer knives, or any of dozens of shaped knives for log or beam molding. Yes it costs about $5K, but can work on a number of 2 rail mills like Logosol, Woodmizer, and others. I plan to get one in about a year. They can come with Gas engine or electric, but so far those sold in the US have all been ordered with gas engine so far. Here's a vid from Norwood:
