As of now, I own two flat top makeup brushes.
The first one I purchased from Sophie&Christine of B&M (linked if interested). :) They sell the Charm brushes ~ which are great and reasonably priced. I definitely recommend checking out the mineral makeup too (Monave).

The second flat top, I purchased recently...
The famous EDM flat top brush. :)
I bought it from ebay.ph, seller: organice07. I'm not sure if she still has the EDM flat top and kabuki brushes. These stuff sell like candy. It took me four tries to get one actually and from different sellers (multiply and ebay).
Before I buy, I ask what's the difference between a flat top and a kabuki brush... and I always get the same answer. So I think I should share the knowledge with you in case you were kept in the dark all these days/weeks/months/years of kalandian.
The kabuki brush is used for light to medium coverage (heavy is achievable but takes a lot of layering and time). The flat top brush, on the other hand, is used for medium to heavy coverage. :) The flat top picks up more product than kabuki and it's usually used with powder products.
[I feel so knowledgeable :P though I'm not.]
Lemme review the pretty brushes:
Charm flat top (500php from B&M): I remember how excited I was to receive this (what a noob, :P).
It disappointed me the first time though. It shed and bled like maaaaaaad during washing and makeup application. It annoyed me more whenever I picked the hairs off of my face. I gave it a chance though, I kept using it with a firm belief that the shedding will lessen to a tolerable degree... but during the fifth washing, it shed a large clump of hair. I stared at the drain it went into for a while and wondered if it was my fault. I wasn't tugging the hairs or anything. I wasn't even rough in any way. When it dried, it looked weird coz it lost a big clump of hair somewhere near the side. I gave up on it after that -- thinking that all the Charm flat tops were like that -- it turned out that it was a defect.
The second flat top I received was waaaaaaaay better. It did shed a few hairs but not as bad as the first one. I was told that animal hair really sheds. I've been using the second flat top for almost two months, I think. It's been great and it doesn't shed on my face but it sheds one or two during washing.
I like the thick handle coz it gives great control but I'm not very fond of pink. The color will grow on me someday. :P
Everyday Minerals flat top (550php from organice07): this brush is suuuper soft. I can't deny that. It hasn't shed a single hair since I received it. It's slightly smaller than the Charm flat top that's why gripping it needed some adjusting since I was used to the Charm's thick handle. I think I tend to use more product with the EDM flat top though. Now I know why it's one of the favorites of MMU users. :)
