Sound Advice: Good deal collectible 'Star Wars' portable projector is

Q: Nebula Cosmos has released a "Star Wars" edition of its Capsule II 720p projector. Painted to resemble R2-D2, it sells for $699. Is this just another gimmick aimed at "Star Wars" buffs?

A: I actually am very fond of the Nebula Smart Projectors. They are complete entertainment packages that bring big-screen experiences to everyone, and they include high-quality sound and autofocus as well as LED light sources, meaning there are no expensive lamps to replace. They make good business projectors, as well.

The "Star Wars" edition of the Capsule II sells for a $120 premium over the regular version. If you want a Capsule II projector, I think the collectible R2-D2 model is worth the extra money. However, if you are looking for a $700 Smart Projector and not a Capsule II specifically, there is another option to consider before you pull out your credit card. The Nebula Cosmos is on sale for the same $699, and it packs a much bigger audiovisual punch.

Though small, the Cosmos is not as portable as the Capsule II and does not have an internal battery. It includes the same Android TV 9.0 operating system and fast autofocusing. It can project a bigger image (120 inches vs. 100), includes high dynamic range HDR10 and is dramatically brighter than the Capsule II. It also has a more potent sound system. If home theater is what you are after and you can plug it in, the Cosmos is the way to go.

For the "Star Wars" fan, the R2-D2 Capsule II is a perfect go-anywhere machine, not to mention a great conversation starter. What better way to wake up a sleepy crowd at a business meeting than putting R2-D2 on the middle of the table?

A good compromise between the Capsule II and Cosmos is the Nebula Solar Portable. It combines the portability and battery power of the Capsule II with the 1080p resolution and 120-inch image size of the Cosmos. It is on sale for only $519, and though not nearly as bright as the Cosmos, it is noticeably brighter than the Capsule II. Check them all out at seenebula.com.

Q: I bought the TLOVII Sonic Electric Toothbrush you reviewed and I love it! I want to buy more as gifts, but in your column two weeks ago, you said that they were sold out. I also can't find TLOVII brush head refills. Do you know when they will be available again? Do any other brush heads fit?

A: The toothbrush is finally available again on Amazon at $29.95. I was told the brush head refills will be available again in about eight weeks, which gives you plenty of time because the two included brush heads should last at least three months each. The Philips Sonicare HX9023/65 heads are said to be compatible with TLOVII, although I have not tried them.
