The Ridgid R4510 portable table saw is large enough to rip sheets of plywood in half, yet also earns high marks for easy mobility on its gravity-rise folding cart. Reviews say it has plenty of power, and both the miter gauge and the micro-adjusting fence provide good accuracy. The blade guard (with riving knife) also earns good reviews. One lever adjusts the blade's bevel and height; the height can be locked. A 2.5-inch dust port can be hooked to a shop vac. Most comparison tests rank the Ridgid R4510 as a good budget value, because it performs as well as the more expensive Bosch 4100-09 (*Est. $550) , which offers quieter operation and a more convenient blade guard -- plus an arbor lock for tool-free blade changes.
We found the largest and most current comparison tests of the Ridgid R4510 table saw at Popular Mechanics. The comparison review in the 2011 Taunton Tool Guide covers fewer saws but provides more detail about precise test results. We found useful comments and ratings from owners at HomeDepot.com, plus a few at Amazon.com. The Ridgid Tool Forum also has a long, detailed thread with comparisons between the Ridgid R4510 and the Bosch 4100 series of portable saw.
The Ridgid R4510 earns the budget-buy spot in this roundup review that reports on tests of 11 portable table saws. After test cuts on 2X lumber, plywood and oak, editors say the Ridgid "cut with formidable power and grace." The Ridgid's wheeled stand also earns kudos here. The main drawback -- aside from not having an arbor lock or digital fence -- is the way a tab can obstruct the fence.

2. Taunton's 2011 Tool Guide
The Ridgid R4510 earns the Best Value award in comparison tests of six portable table saws. It's the loudest saw tested, but the controls are judged good, the riving knife/blade guard very good and the miter gauge the best of the lot. Testers also like the controls on the Ridgid and call it a good value, especially considering its mobile stand. Readers of Fine Woodworking and Fine Homebuilding rank the Ridgid third, after the Bosch 4100-09 and the DeWalt DW744X.

5. Ridgid Power Tools Forum
This comparison of several Ridgid and Bosch portable table saws is based on inspection in a store rather than through testing or usage, but still provides quite helpful information. When set up, the Ridgid saw is 3 inches shorter than the Bosch -- so the better choice depends on user height and comfort. The Ridgid isn't quite as convenient when it comes to blade changes and table release; nor are the blade guard and riving knife as convenient as on the Bosch. The Ridgid has the edge when it comes to cutting depth (cutting a 4-by-4 in one pass) and convenient blade adjustment. Quite a few other readers contribute their experiences with the Ridgid as well.
