John, 3620 does not come up on Makita's web site. Is this a used router? The 3621X is only a 1-1/4 HP plunge router, and I think you can do much better. Most people dont want to spend a fortune on their tools starting out. Keep in mind that a router will do so many of the woodworking tasks that it is very important to get one with some common features. This is my recommendation: You will want a router in the 2 HP and up range. This will give you the ability to use larger bits or more aggressive cutting bits. You will want a plunge router to allow you to make quick depth adjustments during cutting operations. You need the ability to use guide bushings to follow templates. You also need the ability to easily mount and dismount your router to a table. You should buy one of the quality brand names to avoid early router failure. All that having been said the easiest way to get all these features is with one of the combo kits. These kits have both a fixed and a plunge base, one motor, and usually an edge guide. Most will accept Porter Cable style guide bushings. Popular choices are the Hitachi KM12VC, Porter cable 694VK or 895PK, DeWalt DW618PK, Makita RF1101KIT2, Craftsman 26620, and my personal favorite the Bosch 1617EVSPK.
All of these kits will perform well, expect to pay around $200. Take the time to read the many posts on choosing a router to learn more specifics about each. The most important thing is for you to feel comfortable with the router. Before you spend your money put your hands on the router and see how the controls adjust, both right side up and upside down(as in table mounting) You can spend less, as little as $63 for a Skil 2-1/4 HP plunge router at HD, but keep in mind that you do get what you pay for.
