I have 6, 2 that take different bases. 2 laminate trimmers one taking 2 different styles of bases 2 fixed bases models of the small full size type - around 1hp, a 1-1/2 hp plunge or fixed base model with a couple modified base plates, and a 3-1/4hp plunge. They all serve their purpose. Most of mine are Porter Cable but they go back before they were sold off to DeWalt. When I got mine Bosch and PC were the 2 most common in my neck of the woods. Festool then probably had more people choke on their coffee upon seeing or hearing the price than they do now, but if you got a burn happening in your wallet....
For all around use a plunge is likely going to be the most versatile for you, if you can't go for one of the 2 in 1 kits.
