I'm in a similar situation as yourself, but I actually sprung for the free promotion that EdenFantasys had on their bullet vibrator despite wanting to start off nicer myself. From reading the reviews beforehand, it said it was strong and relatively average in volume despite being cheap and I couldn't ask for a better start, so I took advantage of it.
Although, as much as I want to recommend the higher end products by Lelo, We Vibe, Je Joue and so forth, I think it would be better to start off with that free promotion or perhaps a cheaper clitoral vibe, and if you are very curious, maybe a g-spot vibrator.
The reason I say this is because, you never know quite how your body will respond. I, for example, was always told vibrators were the best things ever, but the first time I used a vibrator, admittedly, I thought it was quite powerful and was more than excited, but by the end of using it, I had a very hollow orgasm and wasn't very satisfied. It took some messing around and understanding my previous masturbation sessions make it work for myself, and regardless of what toy you start off, you may or may not reach that instant success depending on numerous qualities of both yourself and the kind of vibrator.
So, maybe it's just me, but you don't want to start off with a high end vibrator and have the chance of not enjoying it or discovering vibrators just don't work for you, should worse come to worst, and having blown a huge sum of money on it. What you SHOULD do is start off with some midrange, cheaper vibrators of varying intensities and materials, and if there are any you are partial or impartial to after you are finished experimenting, you analyze them and decide from there what works best for you if at all.
After browsing around, here are my recommendations (aside from the promotion):
Silicone clitorial vibrator, 3 vrooms/2 bees:

Silicone clitoral vibrator wired bullet/egg, 4 vrooms/ 2 bees:

Silicone clitoral vibrator, partially insertable, 3 vrooms/2 bees:

Plastic clitoral vibrator, partially insertable, 4 vrooms/2 bees:
link
Silicone g-spot vibrator, 3 vrooms/2 bees:
link
Plastic traditional vibrator, 3 vrooms/3 bees:

Mind you, I don't expect you to buy all these things or even one, but I tried to choose things that had safe materials, decent bees and vrooms, were modest in shape and girth, and some, like the last, had extensive features like a variety of patterns for more affordable prices. Of course, I say anything is a good starter if it's under 50 dollars (for each toy), should you browse some more and find something that catches your fancy.
Word of advice, though, I did put in an egg/bullet vibrator simply because compact hand held ones like Mimi or Siri come at a pretty hefty price tag so, if you don't want to go with one of those, there ARE wireless eggs and bullets you could check out before splurging on one of the higher up toys. I didn't recommend any pocket rockets at the moment though, since those are better for travel rather than extensive use since they are flimsier and don't have as long of a shelf life.
I hope this helps! Sorry for the long winded response.
