I agree 100%!
There are so many inexpensive QUALITY toys that are good for beginners. Your first vibe doesn't have to be a luxury vibe, but anything that's crap, should never be recommended to beginners! My first sex toy was one of those, and it was so disappointing, I didn't try again for years.
To me a beginner toy should be presented in a friendly and sex-positive manner, as Cherrylane said, be easy to use, and be well-made. I'd say also, being under $30, though of course that's going to vary depending on the beginner. A career woman looking for her first vibe will have more money than a college student, most likely.
As for vibration strength, a too-strong vibe can be muffled by using through clothes or not directly on the clit, but there's not much you can do to make a too-weak vibe feel stronger. A weak vibe may be fun for foreplay or teasing, but I imagine most beginners looking for their first vibe want something for orgasms.
For beginner vibes, I'd recommend the classic "egg with a remote pack", a pocket rocket style, or a simple bullet for women wanting external stimulation. For internal, there are many affordable and well-reviewed rabbits and G-spot vibes.
But if the toy is a piece of junk, it's junk, and shouldn't be foisted off on beginners.
