Welll....in fairness, I do not have experience with either of these products. While I do like to use some types of cable like equipment at the gym, I still rely more upon free weights for strength training.
If you plan to go the home gym route consider purchasing 15lb and 20lb dumb bells for now and visit
www.exrx.net. for beginning ideas. As your budget allows, you may think about adding a TRX suspension trainer. This takes up much less space than the Total Gym. These things are great for most levels of conditioning and will also help you build core strength as well. Most trainers would agree that it is much better to do compound exercises where you standing or on your feet (closed chain exercise) than where you are seated as would be the case with some of the home gym cable machines. The exception to this would be if you are rehabilitating a particular body part and should be standing or need to isolate a specific muscle group. This is a link to the TRX trainer just get a look at what you could do with it.

You can also find many exercises for the TRX on youtube for ideas too.
In the meantime, you can purchase a physio ball to help build some beginning core strength, and it can also serve as a bench while your are doing chest presses with those new 20lb dumb bells.
Another item I would suggest for your cardio is a jump rope...A yoga mat might me nice too if you are familiar with different asanas (poses)
Just a few thoughts...
But overall, I would be very cautious about purchasing a large piece of equipment that might not be as versatile as your fitness needs progress.
