At the risk of being construed as having vendor bias, I'll give you my take. When you drive a Cruiser fitted with EPS, you can't tell the difference from hydraulic. If anything, the level of assist is more precise because it's monitored by a computer. You can even tune it to the level that suits your liking by turning a knob.
Installation is non-intrusive. Nothing is disturbed, and nothing is added under the hood. These days who wants to hack up a Cruiser? A vehicle is only original once. The fact that the original tie rod system is retained isn't necessarily a bad thing. Tie rod end kits and center arm rebuild kits are readily available. It's a vintage system that will keep on working if maintained.
Parts availability is a key consideration. The once common mini-truck, FJ60 parts are rapidly dwindling in supply. Scout parts are even harder to come by. You're often dealing with tattered used parts. If you need replacement parts down the road, your option will be limited. For this reason, many of my shop customers who used to perform such conversions have been switching to EPS.
Regarding cost, when you need to consider the total cost including the effort to source parts and the labor to install, EPS is quite competitive. Among EPS solutions, there are budget solutions and there are turn-key solutions. I've been asked what's the difference between the $655 ePowersteering kit and the City Racer kit. Well, it's be covered in other threads here, but here's the short version. The
ePowersteering kit isn't a drop-in solution. They don't provide a steering column. You have to cut your old column to fit it. The motor is a rebuilt unit, not new. Installation is more difficult, and the end result won't look quite as sleek. See comparison photos below.
