I really cannot "recommend" a tripod under $100. There are lots of them... I just don't recommend them.
The failure rates are usually high and the failure can cost you the gear ... but more often the tripod breaks and you have to buy another. Even when they haven't failed, they are not particularly solid. I have a friend that is on his 3rd "cheap" tripod and I've pointed out that while he claims not to be able to afford a more expensive tripod, he's already spent the money re-buying his "cheap" tripod 3x over.
Manfrotto has their "BeFree" line and there are also the "MeFoto" tripods which are relatively inexpensive... but even the least expensive of these start at around $150... and they don't really get into the decent quality until you get nearer to $200.
Benro makes their TAD18AIB1 tripod & head... it's an aluminum tripod with 4-section legs with flip-lever locks, and it comes with their B1 size ball-head. It's normally $190... but it's on sale for $170 (that's the price I see at
B&H Photo anyway). I have had several Benro tripods, heads, and monopods so everything has had solid quality. They make the same tripod with the B2 size head (which can handle much more weight). The heads are screwed onto the leg assembly with the single 3/8" 16 bolt... which means you could get the cheaper B1 head... and then upgrade to a B2 head later (or just buy it with the B2 head ... it's only a little more money).
Basically I consider the $200 price point to be about what people should expect to spend to get a decent entry-level tripod. You can get an entry level tripod for less... but it wont be "decent"... it wont be very solid and may break more easily than you might guess.
