I have no personal experience dealing with Winds101. I've heard both favorable and unfavorable comments. There have been a few mentions of Winds101 and Liz (the owner) on this board. If you search from the Fluteland main page, you should find a few comments. As far as I knew, Winds101 is a small one person operation that operates solely as an online store. I am not aware of a brick-and-mortar store - just their website and presence on eBay and Reverb. There is one review on Yelp.
The Fluteland FAQ (under the general category) lists a number of reputable flute vendors you could consider:
Getting a few different flutes on trial is an excellent idea. When I went shopping, I fully intended to buy a Powell flute because that is what the local professional flutists were using and recommended to me. When I tried the Powells, they played very well but when I tried the Muramatsu, I was blown away by everything about it - the sound, the feel, the ability to play it with varying colors, and the ease of playing it. I frequently use use this analogy when recommending flutes: They are like shoes. You have to buy what fits you or you will be uncomfortable and unhappy. There are many different excellent flute brands. I personally like the Muramatsu flutes best, but I can't say for sure that a Muramatsu will be the best for YOU. Look at the list of flute brands in the FAQ. If possible, try to visit a major flute store and try as many as you can.
Another good option is to try to find a regional flute festival that you can attend. Most often, a number of big flute vendors will be there and have dozens and perhaps hundreds of flutes available to try. The National Flute Association also has a national convention each year and every major flute vendor is there in force. However, you must join the NFA to attend the convention and there is also a substantial fee to participate in the convention. I've attended a few of them over the last 10 years and found them to be an enjoyable and worthwhile experience. There will literally be thousands of flutes on display that anyone can try or buy.
