How much is it in total? Acutally EOS300 is not a new model, it has been launched since 2000(if I am not wrong). Its the introductory SLR camera for Canon Series.

Strong point: fast focusing speed
very light
cheap
semi-pro metering system

Weak point: plastic mount
too light to hold heavy lens
size a bit small(i think its designed for female hand size)

Comapring its price and value, I think its a very good buy for your first SLR. If you update your camera in the future, EOS300 can still be used as a backup body.

The two lens together with the camera are definitely not good. You may consider to buy better lens if you have spare money in the future.

p.s. I heard there is one model called EOS300V. It is the enhanced model for EOS300. Faster focusing speed, metal mount.
