Andris, So first off, I don't think that the only metric for comparing products should be lowest cost, and it is an apples to oranges comparison, as the YaMoRC booster works with RailCom, while Digitrax boosters do not. Digitrax also has unusually inexpensive boosters,?especially the DB220 dual 8A booster. That being said, I don't think your cost comparison is fair. Most boosters in the industry cost US $30-$40 per amp, and the YaMoRC YD7403 falls within this range at? $36.43 per amp including RailCom. On a raw per-amp basis including a Meanwell power supply, the DB220 costs $14.44 per amp, when you add 4 PSXX circuit breakers (2 breakers?per booster output) the cost is $26.94 per amp, and if you go to 3 PSXX breakers per booster output, the cost is $33.19 per amp. So there's no perfect apples to apples comparison, but you should be able to get better utilization out of the DB220s. When you compare the YD7403 to ESU and Digikeijs, it compares?favorably cost wise. Any of those are cheaper than NCE's boosters,?which don't even have RailCom. The new TCS B-106 costs an astronomical $61.67 per amp, but it has Lenz-quality power output, LCC tie-in, current limiting on startup, and a global RailCom reader, so it's more of a high end product. The only thing that can even come close to the DB220 on a cost basis is the Tam Valley booster at $25 per amp, plus it has a peak capacity of 5A, which would put it at $12 per amp, since boosters are often sized for peak startup loads. Neither support RailCom in any way. So my conclusion is that the YD7403 is competitively priced and appears to have a great featureset making it attractive at that price point, but it's not as cheap on a per-amp basis as Digitrax and Tam Valley boosters.
