Of late, the manufacturers of the digital SLRs are coming up with new cameras that are capable of capturing HD videos. Naturally, the users of these cameras can now capture high quality videos which were not the case with the previous cameras. However, there is one problem in this regard. Often, these cameras fail to produce crystal clear videos because of the lack of necessary accessories. These accessories are generally very expensive. Naturally, the common users think twice before using them to capture high definition movies.

Nevertheless, the demand for HD videos in the DSRLs is increasing. Consequently, some companies are coming up with new technologies that will enable the users to capture high quality videos at a very reasonable price. So, there are some affordable accessories designed to capture professional quality video are now available in the market.
RigWheels is just one great example of that. This is a good camera dolly available at a very affordable price. Rigwheels enable the users to capture the sliding shots at great ease and without hampering the quality of the video. In fact, the effect it creates is similar to the more expensive dolly and track devices that are used by the professionals.
Each of the RigWheels has one bolt attached to rubber coated wheels for smooth movement. The user has to attach these wheels to the camera using the bolts. The DSLR can be mounted directly on the wheels or it may first be mounted on a carriage where tripod is attached. Then, the camera can be moved easily on a smooth surface, track or rail.
RigWheels are sold in packs each of which generally contains 3 or 4 wheels. According to the manufacturers, these wheels are extremely smooth because of their specially built wheels.
RigWheels will cost you around $140 and that is not a cheap price anyway. However, it is cheaper than the professional dollies and also, it is easier to carry along.
